Context

“"It seems to me that man would have had no prospect of any special praise, if he were able to lead a good life simply because there was none to persuade him to lead an evil life; since both by nature he had the power, and in his power he had the will, not to consent to the persuader." Reply Obj. 3: An assault is penal if it be difficult to resist it: but, in the state of innocence, man was able, without any difficulty, to resist temptation. Consequently the tempter's assault was not a punishment to man. _______________________ SECOND ARTICLE [II-II, Q. 165, Art. 2] Whether the Manner and Order of the First Temptation Was Fitting?
